Nitrous Express 8 Cyl VXL Direct Port 4 Solenoids Nitrous Kit (200-500HP) w/12lb Bottle

If you're looking to significantly increase your 8-cylinder engine's horsepower, a direct port nitrous system like this one from Nitrous Express is a serious consideration. This kit is designed to inject a precise mixture of nitrous oxide and fuel directly into each cylinder's intake port, offering a more consistent and powerful boost than a single-point fogger system. It's engineered to add anywhere from 200 to 500 horsepower, depending on the jetting you choose and your engine's setup.

What sets this system apart are the NX Lightning Series solenoids. They feature an improved internal flow path where nitrous or fuel enters above the seat and exits at the bottom, which Nitrous Express claims is unmatched by other solenoids. The nitrous solenoids have a built-in purge port, allowing you to connect a purge valve directly to the solenoid body. This setup helps eliminate air pockets between the purge valve and the solenoid orifice, ensuring a cleaner nitrous delivery. For the fuel solenoids, there's a bypass port that lets you connect a small return line to the fuel tank. This helps prevent trapped air between the fuel pressure regulator and the solenoid, reducing the risk of lean spikes. The solenoids themselves are well-built with CNC-machined aluminum bodies and carbon fiber tops for a strong yet lightweight construction. Nitrous Express uses high-quality, USA-made components for these critical parts.

This comprehensive kit includes everything you need to get started, such as eight extended-length VXL nozzles, the two nitrous and two fuel Lightning solenoids, anodized aluminum distribution blocks, and 3/16-inch stainless steel hard lines with nickel-plated fittings. It comes pre-jetted for 200-500 horsepower gains. You also get 6AN nitrous feed lines, a high-flow Y-fitting, a wide-open throttle switch, 40-amp relays with harnesses, a master arming switch, stainless steel bottle brackets, and a 12-pound nitrous bottle equipped with the NX Lightning bottle valve. Remember that this system is not CARB approved and cannot be shipped to California.
